  • Rails - handling global site settings

    - by egarcia
    I'm developing a new rails application which is supposed to be installed several times in order to implement several sites. There are some things, like the "Site Title" or the "Default Number of Items per Page" that clearly belong to a "global settings" table / config file. I've made a list of the things I think I'll need: ActiveRecord model that is capable of: Storing different kinds of data. I suppose this would be accomplished encoding the values on a string on the db, probably with a "type" field. Indexing settings by name Validations based on a "type" attribute (i.e. don't accept invalid dates on "date" settings) Validations based on a allows_nil property. A controller that allows me to change settings via views. I'm pretty sure I could implement this myself, but I'm not willing to reinvent the wheel. I've done some searching, but I could only find rails-settings, which doesn't really serve me: I need a proper model & controller so I can use declarative-authorization, and it does not provide any controller or view facilities. Is there a gem or plugin out there that implements what I want, or any library I should look at? Thanks a lot.

  • Send Redirects To Specific Ports

    - by Garrett
    I have an Rails application server that is listening on port 9000, and is being called through haproxy. All my redirects from that server are being redirected back through port 9000, when they should be sent back on port 80. I am using a combination of haproxy + nginx + passenger. Is there a way to make sure all redirects are being sent through port 80, regardless of what port the actual server is listening on? I don't care if its a haproxy, nginx, Passenger, or Rails change. I just need to make sure most requests unless specified otherwise, are sent back to port 80. Thanks!

  • Find model records by ID in the order the array of IDs were given

    - by defaye
    I have a query to get the IDs of people in a particular order, say: ids = [1, 3, 5, 9, 6, 2] I then want to fetch those people by Person.find(ids) But they are always fetched in numerical order, I know this by performing: people = Person.find(ids).map(&:id) => [1, 2, 3, 5, 6, 9] How can I run this query so that the order is the same as the order of the ids array? I made this task more difficult as I wanted to only perform the query to fetch people once, from the IDs given. So, performing multiple queries is out of the question. I tried something like: ids.each do |i| person = people.where('id = ?', i) But I don't think this works.

  • How can I make rake assets:precompile build to the right location?

    - by Micah Gideon Modell
    I'm deploying my Rails 3 app to a subdirectory of my hosting service and therefore I'm using both a scope statement in my routes.rb and a config.assets.prefix. However, this causes my rake assets:precompile to build into public//assets instead of just into assets (since my prefix simply accounts for the scope). I can copy the files to the right location and everything will work, but I'd love for someone to tell me a better way (one must exist, right?). /config/application.rb config.assets.prefix = "/sapa/assets" /config/routes.rb scope "sapa" do … end Any help would be appreciated.

  • AssociationTypeMismatch with Expected Type on Nested Model Forms

    - by Craig Walker
    I'm getting this exception when doing a nested model form: ActiveRecord::AssociationTypeMismatch in RecipesController#update Ingredient(#35624480) expected, got Ingredient(#34767560) The models involved are Recipe and Ingredient. Recipe has_many and accepts_nested_attributes_for :ingredients, which belongs_to :recipe. I get this exception when attempting to _destroy (=1) one of the preexisting Ingredients on a nested Ingredient form for the Recipe Edit/Update. This makes very little sense, mostly because the association types are as expected (by the exception's own admission). What makes even less sense is that it works just fine in a functional test. Any ideas what might be causing this, or what I should be looking for?

  • acts-as-taggable-on find within specific tag context

    - by user284194
    I have two models (entries and messages) using acts-as-taggable-on for tagging. How do I write a find condition for tagged messages from only the one model and not both? The only way I can get the tagged items to display is through the basic find: @tags = Tag.find(:all) But this displays tags from both the entries model and the messages model. How can I find the tags from just the messages model? I'm really new to Rails and ActiveRecord finds. I appreciate any help you can offer. Thank you for reading my question.

  • Set value in controller using nested resource

    - by vectran
    I have two models, product and order. Product - cost - id Order - cost - product_id Each time someone places an order, it captures the product_id through a radio button value in the "new order" form. In the controller when creating the new order it needs to set order.cost to order.product.cost. Logically I thought the code should be something like this: def create ... @order.cost == @order.product.cost ... end However I can't seem to make it work at all, hence me asking the question here. Any help is answering (or naming) the question would be greatly appreciated.

  • Rails shoulda and factory_girl setup

    - by kristian nissen
    I have installed both shoulda and factory_girl, I can run shoulda just fine, but when I add this: require 'factory_girl' Factory.define :user do |u| u.mail '[email protected]' u.pass 'secret' end to my test/test_helper.rb I'm getting this error: /test/test_helper.rb:1:in `require': no such file to load -- factory_girl (LoadError) when I execute rake test:units I have installed both gems using: sudo gem install thoughtbot-shoulda --source=http://gems.github.com sudo gem install thoughtbot-factory_girl --source=http://gems.github.com and can see both of them being installed fine. And by the way, this works fine as well: script/console Loading development environment (Rails 2.3.8) require 'factory_girl' = [] so requiring the gems seems to be working

  • Is this type of calculation to be put in Model or Controller?

    - by Hadi
    i have Product and SalesOrder model (to simplify, 1 sales_order only for 1 product) Product has_many SalesOrder SalesOrder belongs_to Product pa = Product A #2000 so1 = SalesOrder 1 order product A #1000, date:yesterday so2 = SalesOrder 2 order product A #999, date:yesterday so3 = SalesOrder 3 order product A #1000, date:now Based on the date, pa.find_sales_orders_that_can_be_delivered will give: SalesOrder 1 order product A #1000, date:yesterday SalesOrder 2 order product A #999, date:yesterday SalesOrder 3 order product A #1, date:now <-- the newest The question is: is find_sales_orders_that_can_be_delivered should be in the Model? i can do it in controller. and the general question is: what goes in Model and what goes in Controller. Thank you

  • Globalize2 and migrations

    - by diegogs
    Hi, I have used globalize2 to add i18n to an old site. There is already a lot of content in spanish, however it isn't stored in globalize2 tables. Is there a way to convert this content to globalize2 with a migration in rails? The problem is I can't access the stored content: >> Panel.first => #<Panel id: 1, name: "RT", description: "asd", proje.... >> Panel.first.name => nil >> I18n.locale = nil => nil >> Panel.first.name => nil Any ideas?

  • Using Rails 3 and Haml 3, how do I configure Haml?

    - by dpogg1
    I'm using Rails 3.0.0.beta3 and Haml 3.0.0.rc.2, and I can't find where I need to place the configuration lines for Haml (nor what they are in the new version, for that matter). Using Rails 2.3.5 and Haml 2, I would do Haml::Template.options[:format] = :html5 in environment.rb. Or, in Sinatra, set :haml, {:format => :html5} in my main file. But in Rails 3 everything's been changed around, and no matter where I put that configuration line, I get an undefined method or undefined object error.

  • Rails NoMethodError in loop when method exists

    - by Kevin Whitaker
    Good day all. I'm running into a bit of a problem getting a script running on my production environment, even though it works just fine on my dev box. I've verified that all the requisite gems and such are the same version. I should mention that the script is intended to be run with the script/runner command. Here is a super-condensed version of what I'm trying to do, centered around the part that's broken: def currentDeal marketTime = self.convertToTimeZone(Time.new) deal = Deal.find(:first, :conditions = ["start_time ? AND market_id = ? AND published = ?", marketTime, marketTime, self.id, 1]) return deal end markets = Market.find(all) markets.each do |market| deal = market.currentDeal puts deal.subject end Now convertToTimeZone is a method attached to the model. So, this code works just fine on my dev machine, as stated. However, attempting to run it on my production machine results in: undefined method `subject' for nil:NilClass (NoMethodError) If, however, I go into the console on the production box and do this: def currentDeal marketTime = self.convertToTimeZone(Time.new) deal = Deal.find(:first, :conditions = ["start_time ? AND market_id = ? AND published = ?", marketTime, marketTime, self.id, 1]) return deal end market = Market.find(1) deal = market.currentDeal puts deal.subject It returns the correct value, no problem. So what is going on? This is on rails v 2.3.5, on both machines. Thanks for any help

  • Clean Up Controller, Update Item Quantity within Cart

    Hi guys I was wondering if anyone could help me out, I need to clean up this controller as the resulting code to simply update an items quantity if it already exists seems way too complex. class LineItemsController < ApplicationController def create @product = Product.find(params[:product_id]) if LineItem.exists?(:cart_id => current_cart.id) item = LineItem.find(:first, :conditions => [ "cart_id = #{@current_cart.id}"]) LineItem.update(item.id, :quantity => item.quantity + 1) else @line_item = LineItem.create!(:cart => current_cart, :product => @product, :quantity => 1, :unit_price => @product.price) flash[:notice] = "Added #{@product.name} to cart." end redirect_to root_url end end ` As always any help is much appreciated, the code should be fairly self explanatory, thanks :) PS posted it here as well as it looks a bit funny on here http://pastie.org/994059

  • Rails form with a better URL

    - by Sam
    Wow, switching to REST is a different paradigm for sure and is mainly a headache right now. view <% form_tag (businesses_path, :method => "get") do %> <%= select_tag :business_category_id, options_for_select(@business_categories.collect {|bc| [bc.name, bc.id ]}.insert(0, ["All Containers", 0]), which_business_category(@business_category) ), { :onchange => "this.form.submit();"} %> <% end %> controller def index @business_categories = BusinessCategory.find(:all) if params[:business_category_id].to_i != 0 @business_category = BusinessCategory.find(params[:business_category_id]) @businesses = @business_category.businesses else @businesses = Business.all end respond_to do |format| format.html # index.html.erb format.xml { render :xml => @businesses } end end routes map.resources What I want to to is get a better URL than what this form is presenting which is the following: http://localhost:3000/businesses?business_category_id=1 Without REST I would have do something like http://localhost:3000/business/view/bbq bbq as permalink or I would have done http://localhost:300/business_categories/view/bbq and get the business that are associated with the category but I don't really know the best way of doing this. So the two questions are what is the best logic of finding a business by its categories using the latter form and number two how to get that in a pretty URL all through RESTful routes in Rails.

  • Rails activerecord attributes=

    - by vinhboy
    Hi, I am doing this: @person.attributes = params[:person] Can anyone give me a clue as to why doing an attributes= would cause a bunch of SQL to show in my logs? I see a couple of SELECT and even an UPDATE. I swear I am not doing a "save" -- so I have no idea why setting attributes would trigger queries. Is there a before_ of after_ filter I am missing? Thanks.
